Okay so I'm trying to make it so that when Mario dies, the special exit for the level is activated. So far I have ripped off some other peoples work and come up with this:
Code!freeSpace = $218000
macro RATS_start(id)
db "STAR"
dw RATS_Endcode<id>-RATS_Startcode<id>
dw RATS_Endcode<id>-RATS_Startcode<id>^#$FFFF
RATS_Startcode<id>:
endmacro
macro RATS_end(id)
RATS_Endcode<id>:
endmacro
lorom
header
org $
JSL DeathRoutine
org !freeSpace
%RATS_start(0)
DeathRoutine:
LDA $02 ;1 = normal exit, 2 = secret exit
TAX
LDA $0DD5
BEQ Skip
BPL Return
Skip:
TXA
STA $13CE ;activate midway point flag
STA $0DD5 ;activate exit point
INC $1DE9 ;
LDA #$0B ;fade
STA $0100 ;to OW (without blur effect)
return:
RTL
%RATS_end(0)
(If you see any problems in this let me know because this is my first Xkas patch so I just ripped off smallhacker's pallet patch and changed it but I don't know if anythings wrong or not)
So my question is, what byte do I hijack to insert the JSL Deathroutine?.

The death routine is located at $F606 in bank 00. Access it through a JSL, and restore this in your code:
LDA #$90
STA $7D ; hacked code.

I'm sorry, How do I restore
LDA #$90
STA $7D ; hacked code.
in my code? I don't really understand what that means... thanks though.

You just need to add that in your code, preferably at the beginning so that nothing goes nothing (in case you modify A).

That's the code you overwrote by JSL DeathRoutine, which means that it doesn't exist anymore and that you have to put it somewhere else to have it executed. I haven't taken a closer look at your code, but putting it after the "Return:" label should probably work.
EDIT: Oh yeah, putting it at the beginning sounds better.

alright cool, Thanks.
P.S. Iceguy, your totally the guy I ripped off for this code 
P.P.S Okay so the hack works, Almost... I can't get it to activate the secret exit, just the normal exit. I tried changing LDA $02 to LDA $01 but without any success. While I could fix this by making the real exits secret exits, I would like to know why this is happening.
